Same source - different binaries

Posted by kechthom on 2019-08-22 08:44

Hello,

I did a project half year ago and didn’t change the source-code since that. Now it was necessary to newly compile the code because of the need of an hex-file (up to that moment only .bin and .elf file existed). Because my workstation changed, I had to newly install SW4STM32. But when I looked on file-size after compilation I recognized that binary size increased from 71kB to 73kB. I’m a bit unsure of this behavior. Could the reason be a newer compiler-version or something like that?

Thanks for your answers!

Hi,

I’m not expert in gcc, I can’t give you the exact answer but if it is exactly the same project with the same sources, the size difference probably come from the compiler (behavior of debug optimization, debug symbols, size optimization, clearing unused code... might change on the newer compiler).

Regards,
Kevin.

Sometimes with the update comes compiler toolchain update. I noticed that new toolchain generates different code. IMHO no issue and nothing to worry.
